May I know why use the bypass source from the main water supply and not from the tank? Coz I find that once the main water supply travel to 2nd floor, the pressure drop lower than if it's bypass direct source from tank.

if your main water pressure is weak. then do water tank bypass.

some people use solar heaters, solar above tank level, if do tank bypass, water cant go upto solar

may i know any replacement part for tis Presure sensor ?

rm400 for 2 year only

model : Huba 501.917013181

if got , pls call 0122889683

many people are worried, water pumps could burst their pipes at home. Here is an interesting video i came across, it took 78bar of pressure to burst buteline pipe.
Regular household pumps are 3 - 4bar+ only, it is quite impossible for household pumps like teral or grundfos to burst pipes. It will only leak if the joints are not connected properly.

The problem here is the joints and glue, rarely do our local plumbers follow as high a standard.

Still confused whether you need to get a water pump or not for your new house? Here is some info


I have many customers told me,

1) Plumber say test water pressure first, not necessary need to get pump.
As explained by GOOGLE, water is flowing down from the tank and every 10m drop = 1 bar pressure. 1 storey is approximately 3m, so if u your house is 3 storey high, your ground floor will only get 1bar or pressure while highest floor is 0.3bar, all landed houses the same unless your are using direct water supply and not from tank, that it depends on incoming pressure of the area. SO, no need to test, confirm is weak.

2) Plumber advise to increase water tank height or make the pipe bigger to increase pressure.
As tested, every storey drop (3m) u will only get additional 0.3bar of pressure, how high can u increase the tank? max u can increase 1 to 2ft, impossible to increase the height by additional 1 or 2 storey (6m). Any modifications would not result in significant pressure increase. So, dont waste money

Bought Grundfos UNI-E 5-4 from zheilwane, good price, fast response and a happy customer

thanks bro always try by best to provide best service and price

Hi, can u suggest a good grundfos model for double storey house with 3 bathrooms equiped with 10 inch rain shower?

I read someone recommended CM-PM model, and some recommended CM-PT model. What is the difference between these two? And which exact model is suitable for my house?

Thank you.

[EDITED]

Seems like Ive found the answer after further reading the old reply. Gonna buy CM3-5PM from Lazada. But still got more questions.

What kind of house piping suitable for this pump? Scared that it will leak/blow after installed. My house is a new house, but still wanna make sure everthing will be alright.

For installation, my plumber quote me RM150 only for pump installation. Then he said it is just a normal in and out installation. Is it ok?

I want a professional to install my pump. Dont mind the extra fees to be paid. But cant find a good plumber here in Changlun, Kedah. Anyone can suggest good plumber that cover Changlun area?

Found an official Grundfos supplier in Alor Setar but they didnot provide installation for Changlun area.

@zheilwane
if based on what you mentioned where the pressure should not cause the pipe to burst, is it okay to leave the pump on 24/7?

my previous house with GI pipe got minor leak that we could not find it. so we turn it on when we shower only

for my new house staying about 6 years already, we leave it on 24/7, only off when we going for vacation.

Bought a Teral water pump from @zheilwane based on his advice. Bought a model which is equivalent to Grundfos CM3-5PM and is cheaper than the Grundfos.

Based on my observations after after weeks of using it, it is definitely silent (as silent as Grundfos), the pressure is very good and the water boost is more 'instant' compared to my previous Grundfos CM3-4PM.

My old Grundfos had a 0.5 sec delay before the pressure kicks in when I turn on the tap. So far very happy with the purchase and the plumber did a very good job installing it and doing a pump bypass.

Thank you @zheilwane for the excellent service and price!

anybody can recommend a contact to repair water pump?
i have been using a grundfos pump for 7 years and it died on me.
changed to a new scala 2 model.
sent my old grundfos pump to original service center and got a quote for approx rm800. about half the pump original price when bought it 7 years ago.
crazy. some electrical thing they claim.
pls pm me if anybody got any decent contact for pump repair (CH2-50PC Model) pls.

may b u can share the quote here, then we know what is the problem and how much

diagnosis:
Upon check at the pump found the PC15 no output voltage.Further tested the capacitor , capacitance is low value at 6uF out of 10uF cause the pump failed to start.Besides of this, found the cable entry cracked, request to replaced for safety purpose

PM 1 15 1x230V 50/60Hz bulk GAS IT - RM482
Cable Strip (2m) 3Cx1.5mm2 3pin & 5mm - RM19.50
Kit, Capacitor 10µF 400v - RM74
Service & Labour - RM150

Total RM725.50

If I do not proceed with the repair, I still need to pay RM50 for their 'checking for repair'.

i think it's a rip off personally.
